A1
Abstract:
A control unit executes: a first step S1 of analyzing image information to detect a point at which a height position in a prescribed region of an installation space T1 is highest; a second step S2 of detecting the surface area of a part of which a difference in height position compared with the highest point, at most equal to a prescribed distance from the highest point, is smaller than a pre-determined first threshold; and a third step S3 of recognizing that a workpiece W1 is present at the highest point if the surface area satisfies a prescribed condition; where the prescribed condition includes determining that the surface area is larger than a pre-determined second threshold.
